IMPROVEMENT IN HYDRANT-VALVES. I

Specification forming part of Letters Patent No. 193, 188, dated July 17, 1877; application filed June 25, 1877.

To all whom it may concern:

Be it known that I, FREDERICK SHRIVER, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and Improved Hydrant-Valve, of which the following is a specification:

Figure 1 is a longitudinal section of my improved valve taken on line a; a; in Fig. 2. Fig.

2 is an inverted plan view.

Similar letters of reference indicate corresponding parts.

The object of my invention is to construct a hydrant-valve that cannot freeze or become obstructed so as to be inoperative.

In the drawing, A is a metallic casing, into the lower portion of which the part B is screwed, which projects upward into the said casing, leaving around it the annular chamber a. The part B also projects below the casing A, and is bored longitudinally to form the water-passage b and to receive the valve 0. The bore of the part B is of two diameters, the upper portion that contains the valve 0 being largest. A valve-seat, c, is formed in the part B, against which the valve 0 closes. Above the valve-seat c openings d are made through the sides of the part B, and passages e are formed in projections on opposite sides of the part B, which extend downward below the casing A,.to permit the escape of waste water. The valve 0 consists of a follower, which is reduced in diameter to'receive the packing f, which caps over its end and extends upward to the shoulder g, which is undercut to retain the edges of the packing. Below the packing f a centrally-perforated disk, h, is placed, which is provided with a lip around its outer edge that projects downward. Below the disk h there is a leather or rubber packing-disk, i, and a screw, is, passes through the disks h 'i and packing f into the follower, holding all of the parts together. Above the shoulder g the follower is reduced in diameter to permit the waste to escape through the passages 0 when the valve rests on its seat.

A rod, D, is screwed into the valve 0 for operating it. The part B is connected with a supply-pipe, and the casing A with the upper portion of the hydrant by the pipe E. When the valve 0 is raised it closes the waste passages e and allows the water to pass from the passage b through the openings to the chamber a, and thence through the pipe E. When the valve is closed the water remaining in the pipe E escapes through the waste-passages e, and should one of the passages become clogged the other is suflicient for the escape of the waste water.

The valve-casing, as shown, may be made partly from pipe-fittings, or it may be cast entire from steam metal or other suitable material.

Having thus described my invention, I claim as new and desire to secure by Letters Patentv 1. The part B, containing the valve-seat 0, and having one or more lateral openings, (1,

and passages e, the casing A, having the annular space a, and the valve 0, in combination, substantially as shown and described.

I 2. The valve U, having the under-cut shoulder 9, packing f, metallic disk h, and packing-disk i, substantially as'shown and described.
